21 Claims. (01. 271-21) This invention relates to manifolding devices for typewriters or any similar mechanism employing a plurality of sheets which are to be written upon in superimposed aligned condisheets on the aligning-mechanism to discharge them as a unit and in aligned condition.

Itis a further object to provide a common, intermittently driven power means for inter mittently actuating the unwinding, supplying and aligning means, all within a common casing where the apparatus is protected from dust, dirt and interference with the operation thereof.

It is a further object to provide a cover for the casing, a part of which forms the base support, and aligning mechanism for holding the machine, such as the typewriter, or other mechanism, in a predetermined position with respect to this paper delivery and aligning mechanism.

Referring to the drawings:

Figure 11 is a detail view of an aligning stud, its chain and sprocket.

Referring to the drawings in detail, 1 is a side plate which is mounted upon a bottom 2. 3 is the other side wall. 4 is the front wall. 5 is the rear wall constituting a door. On top of the enclosure is mounted a detachable plate 6 having upstanding, U-shaped, spaced lugs 7 for positioning the typewriter or other similar apparatus which is utilized to work upon the aligned, cut sheets as delivered from he machine of this invention.

Paper supply A paper supply roll on which are rolled a plurality of sheets, is designated at 8 and is mounted by an axle 9 at either end upon-a pair of spaced, diagonally-disposed, supporting rails. The roll is rolled on the bottom 2.between these rails until the axle 9 rides on the edge 10 of the rails, whereupon it rolls up the edge until it rolls up a slot 11. The rails are provided with a horizontal portion 13 on'which is slidably mounted a retaining hook comprising a sliding plate 14 having slots 15 in which are mounted guiding studs 16. At one end is a hand piece 17 and at the other end a retaining hook 18 which can be pulled down to partially encircle the end of the axle 9 which projects through the slot 11. These rails are supported on cross rods 19 and 20 carried by the side walls of the casing. On the upper cross rod are pivoted the arms 21 carrying the brake roller 22 between them. This roller rests upon the sheets at the point they make their departure from the roller 8. There is shown in the drawings a plurality of such sheets, designated 23, 24, 25, 26, 27, 28,29 and 30., Any number of sheets may be employed.

Full 017 mechanism One of the sheets passes between the pull off rolls 31 and 32 which are geared together by the gears 33 and 34. This sheet 30 also passes over the roll 35 beneath the roll 31 and thence upwardly over the roll 32. The remainder of the sheets are formed into a loop while the sheet 30 after it has served its function of unwinding the roll 8 likewise passes into a loop as indicated and the sheets pass in a superimposed group over the guiding rod 36 between the guide shoulders 37, over the rod 38 between the guiding shoulders 39a and thence are separated one by one in succession by the rolls 39, 40, 41, Y

42, 43, 44, 45, 46, 47, 48, 49 and 50 depending upon the number of sheets employed.

Each sheet is independently mounted upon the aligning studs 51a. For instance sheet 30 is first mounted upon the studs, moved forwardly a given distance, and then the next succeeding sheet 29 is mounted on the studs on faces of the uppermost sheet. These tracks are suspended from the cross rails 58.

The chains themselves are slidably guided upon the angular supporting rails 59 so that the sheets are positively maintained in aligned condition on the studs and are caused to'travel with the chain without tearing. The cover plate 8 encloses these rails, chains and studs.

The chains are operated through the sprockets on the shaft 60 at one end. This shaft is driven through the gears 61, 62 and 63, stud shaft 64, worm 65 on the motor shaft 66 by the motor 67. The gear 61a on the shaft 60 drives the gear 61b and 610 which in turn drives the gears 33 and 34.

The driving of the shaft through the gear box 68 may be of any desired form but we prefer to use the intermittent complete cycle driving mechanism which is controlled by the handle 69 and is more. fully set forth in our copending application Serial No. 420,267, filed January 11, 1930.

The other end of the chains is supported upon sprockets 70 mounted on the shaft 71 that is carried in the side walls of the casing. These chains and sprockets are mounted between stripping rollers 72 carried upon the shaft 71 that serve to lift the collated aligned group of sheets and deliver them in such condition out of the machine free of the collating pins 51a.

Separating roll mechanism The rolls 31 and 32 are adapted to be spread apart for threading purposes through the operation of the roll shaft 73 which is provided with a cam surface which actuates the supporting plate 74 against the springs 75, the tension on which is adjusted by the setting nuts 76 against the brackets 77. The plates 74 are connected to the pins 78 that pass throughthe brackets 77 and springs and carry the nuts 76.

A knurled head 79 is mounted on the outside end of the shaft 73 to permit of its rotation.

Threading mechanism for separating rolls When it is desired to thread the sheets between the rolls 39 to 50inclusive, the rolls may be lifted pivotally about their pivot shaft or axis 80 which is mounted upon a bracket 81 on the outside of the casing. This pivot 80 carries an arm 82 that has an eye at one end for receiving the pivot 80 and an eye at the other end for receiving pivotally the roll, such as 40. The roll 40 is pivotally mounted within the eye of the member 82 and retained therein by the screw 83.

The free ends of these rolls fit in slots 84 and have for that purpose a reduced throat 85 with a head 86 so that the slot in the side wall receives the reduced throat portion 85 while the head 86 extends on the outside of the casing. A common locking bar 87 is pivoted mounted on the casing at 88 and is adapted to look all the rolls simultaneously by being inserted between the casing and the shoulder 38 of the rolls, adjacent the reduced portions 85.

This locking bar 87 is held in locked position by a spring finger 89 which forces the locking bar with its locking stud'90 into locking engagement with the recess 91 in the side wall of the register.

If it is desired to adjust the chain shaft gear 61 and its gear 62 with respect to the driving gear 63, we have provided the mounting of the gear 62 upon the stud 62a carried in the sw nging plate 62b and positioned by the locking screw 62c.
